Abstract

A composition particularly applicable in forming a protective interlayer of a high temperature, solid electrolyte electrochemical cell (10), comprises an electrically conducting doped or admixed cerium oxide composition with niobium oxide and/or tantalum oxide characterized by the general formula: NbxTayCe1-x-yO2, where x is about 0.0 to 0.05, y is about 0.0 to 0.05, and x+y is about 0.02 to 0.05, and where x is preferably about 0.02 to 0.05 and y is 0, where the electrochemical cell (10) comprises a first electrode (12); an electrically conductive interlayer (14) of niobium and/or tantalum doped cerium oxide deposited over at least a first portion (R) of the first electrode; an interconnect (16) deposited over the interlayer; a solid electrolyte (18) deposited over a second portion of the first electrode, the first portion being discontinuous from the second portion; and, a second electrode (20) deposited over the solid electrolyte.
